The crow thinks her own bird fairest.

Affection can shape judgment: a parent may find their own child beautiful regardless of how others see that child. The crow’s preference illustrates how personal attachment influences praise.

The proverb can also apply more broadly to people’s fondness for what belongs to them or what they have made. It points to a judgment that may be sincere without being impartial.

Use it when someone praises their own child, creation, or possession in a way that seems influenced by affection. It can be gently teasing, but may sound dismissive if the person’s pride is deeply felt.
